Hello,  
In an Allen-Bradley PLC, I have a UDT called Motor. Boolean tags are in that UDT, yet Ignition seems to recognize those Boolean tags only as folders. OPC quick client and the Designer’s OPC UA Server show folders. Directly pointing at the tag has a configuration error. But what is most annoying is that Ignition has no problems whatsoever finding tags in others UDTs. As I re-write the Motor UDT is, there anything I ought to do on the Ignition side? Thanks

This is a weird old bug, I think just in the legacy driver, and you'll just have to restart the UA module or gateway to get the tag to come back in as the correct type.

Nice! Restarting the module did it. Thanks Kevin

In case this helps anyone, it seems to only happen to me when I create the tag in the tag browser before searching the OPC Browser. I had the problem with a standard tag though, not a UDT.
